Where's the sidechain input?

You can access the reduction property and connect it a gain node of anouther source.

That's using the output of the compressor to drive another node. A sidechain compressor has two inputs.

I know what sidechain compression is, yes, you need to code a little bit more :)

Just the BASICS. Like before we knew anything about Audio

Regardless of the other valid reply to this question, the implication that sidechain is a fundamentally basic thing for a compressor is questionable. Sidechains are extremely useful for many cases, but there's clearly tons of applications of compressors that don't use sidechains. It's not like a sidechainless compressor is unusable.
